How Do I Make This Textured Cake Design?!

Okay so my best friend is getting married and I'm making her cake in June! She sent me this photo of the cake she wanted and ican't figure out for the life of me how to make it look like this! I've found textures similar but I really want it to be exactly what she wants! Any tips?

Thanks for all of the responses! Everything you've sent me is getting me closer and closer to that final look! The thing about this texture is that its uniformly sporadic so it's hard to make it look so effortless!
